I just wanted to mention that NetBSD/ofppc also works fine on the Pegasos2 and supports all available devices, including Firewire and Gigabit ethernet.
And unlike Linux or other BSDs we won't abandon Pegasos support. I can guarantee it, because I am the author of the port.
I'm running three operating systems on my Peg2 (MorphOS/OS4/NetBSD).
If you want to try it, download a recent snapshot from nyftp.netbsd.org. The last release (5.1) is old and doesn't boot from Amiga RDB partitions.
